Cabbage Plants in frames need free airing whenever the temperature is above the freezing point, or so long as the soil of the bed is not frozen. Snow, in that case, should be removed soon after its fall. As long as the soil is frozen the snow can safely be left on for a number of days. Cabbage, cauliflower, and lettuce seed should be sown at intervals to secure plants for extra-early sales or setting. A month later they will be ready to transfer to boxes, which should go to the coldframe and be given protection by mats or shutters.
Coldframes must be well ventilated on warm, sunny days; leave the sashes off as long as is possible without injury to the plants. Keep the soil in a friable condition, and look carefully to any possible places where water can stand and freeze. If the frames seem too cold, bank up around them with coarse manure.
Look up and repair the sashes. Save the horse-manure from day to day, rejecting dry litter, and piling up the droppings and urine-soaked bedding in thin layers to prevent violent heating.
Lettuce in frames treat as advised for cabbage plants.
Pruning should now be considered. Perhaps it is best to prune fruit-trees in March or April, but grapes and currants and gooseberries may be pruned now. January and February are good months in which to prune peach trees. Thin out the peach trees well, taking care to remove all the dead wood. If you have much pruning to do in apple, pear, or plum orchards, you will save time by utilizing the warm days now. Study well the different methods of pruning. Never let an itinerant pruner touch your trees until you are satisfied that he understands his business.
Tools should now be inspected and repaired, and any new ones that are needed made or ordered.
Sow seed of Jersey Wakefield in flats filled with light loamy soil, the last week of this month. Sow thinly, cover lightly, and place the boxes in a gentle hotbed or any warm, sunny situation. When the plants are strong, transplant them into flats 1½ in apart each way. As growth begins, gradually expose them to the open air on all favorable occasions. Late in March remove them to a cold-frame, and properly harden them off before setting them in the open ground.
We urgently advise every one who has a garden, large or small, to make a trial of the new celery-culture. You need, first, good plants. Get some seed of White Plume or Golden Self-blanching, and sow it thickly in flats filled with fine loam. Cover by sifting a thin layer of sand or fine soil over it, and firm well. Keep in a moderately warm place, watering as needed, until plants appear. If you have a number of flats, they may be placed on top of one another. At the first sign of plant-growth, bring the flats gradually to the light. When the plants are 1½ or 2 in. high, transplant them into other flats, setting them in rows 2½ in. apart, the plants half an inch apart in the rows. Then set the flats in a coldframe until the plants are large enough to plant out in the open ground.
Hotbeds for raising early plants should be made this month. Always break the manure up fine and tread it down well. Be sure to put enough in the center of beds, so that there will be no sagging. Fresh manure of hard-worked and well-fed horses, free from dry litter, is best. An addition of leaves used for bedding will serve to produce a more moderate but more lasting heat. Sheep-manure may also be added to the horse-manure, should there be a scant supply of the latter on hand.
We urgently advise giving the new onion-culture a trial. For seed, buy a packet or an ounce of Prizetaker, Spanish King, White Victoria, or some other large kind of globe onion. Sow the seed in flats, in a hotbed, or in a greenhouse late in the month, and transplant the onions to the open ground as soon as the latter is in working condition. Set the plants in rows 1 ft. apart and about 3 in. apart in the row.
Make a thorough inspection of all plum and cherry trees, wild and cultivated, for plum-knot. Cut and burn all the knots found. Remove all "mummy" plums, for they spread the fruit-rot.
Give the plants in the garden a heavy dressing of fine old compost. If you wish a few early stalks, place kegs or boxes over some of the plants, and heap over them some heating horse-manure.
A few seeds may be sown in the hotbed.
Cabbage, Cauliflower, And Celery seeds may be sown for the early crop.
Seeds should be sown. Take care that the young plants are never stunted.
Grafting may be done in favorable weather. Cherries and plums must be grafted early. Use liquid grafting-wax in cold weather.
Hotbeds may be made at any time, but do not grow impatient about the work, for there will be cold weather yet. Clean, fresh manure is necessary, and a layer 2 ft. thick should be tramped hard. When once started and the seeds sown, do not let the beds get too hot. Give them air on fine days and give the seedlings plenty of water. Use two thermometers - one to test the atmosphere and the other the heat of the soil.
Lettuce should be sown in the hotbed for an early crop.
Onion seed for the new onion-culture may be sown at the close of the month.
Sow now, if the ground can be worked.
Peppers may be sown late in the month.
Potatoes kept for seed must not be allowed to sprout. Keep them in a temperature near freezing point. Rub off the sprouts from potatoes kept for eating, and pick out all decayed specimens.
Sow some seeds for an early crop.
